The JW's in Beijing. The JW Central is newer by about 6 years & slightly west of the square near subway line 4 which is only a couple stops to the BJ south rail station.
Service is low tone Chinese, but the EL has excellent english speaking staff + great local Chinese food in the morning & in the evening. They even have a couple computers in the EL with VPN's.
The older JW, built for the 2008 Olympics, is on the east side in Chaoyang, Near 4th ring road & about 1 block from busy subway line1. Great western buffet breakfast + the modern EL will have kore western dish's , also with great staff. Nearby is the RC + a large shopping mall.
BTW, both have traffic issues during rush hour.
